It is the oldest of the Western religions started around 2000 BC.
The roots of Judaism can be traced to a covenant through which God formed a permanent relationship with the Jews. This was through the prophet Abraham who is seen as the patriarch of the Jewish people and then the prophet Moses who was given the Torah – law on Mount Sinai by God.
The exodus from slavery in Egypt (the Passover) and the founding of their own country in Canaan established in the minds of the Jews that they were the chosen people of God.
